The University of Alabama had a Univac 1100 Series mainframe when I started school there in 1977. 36 bit, 1's complement. Users primarily used Fortran and COBOL. I personally used assembly language. Around 1985, UA changed over to an IBM 3081 I believe. 32 bit, 2's compliment. Had to learn a new assembly language again.
